A member asked:
Is 250 mg of cephalexin twice a day enough to treat uti in a 60 pound adult woman? its 10 days. i was having trouble with higher dose and with macrobid. thanks?

Some UTI bacteria are resistant to cephalexin and related drugs. If the cause of your UTI is susceptible to it, this dose is fine for a lower tract UTI, i.e. isolated to the bladder. A higher dose would be required for upper urinary tract infection (pyelonephritis). Discuss with your doctor if any uncertainty remains. (Is "60 pound" a typo? Maybe 160 lb?)
